Definitions

  • the invention relates to a rotary screen printing machine for Print large images using multiple relative speeds synchronized circular templates that correspond to a partial repeat optionally liftable from their print position and onto the one to be printed Goods can be lowered.
  • the partial repeats by a round template or group of templates on the goods to be printed e.g. textile materials
  • several similar methods are known to be printed.
  • the individual stencils are over a vertical shaft and individually assigned bevel gear driven so that an individual Control of a single stencil drive is not possible.
  • DE-GM 72 30 388 that on the printing blanket speed synchronized lifting of individual circular templates e.g. by To control crank drives, eccentrics or cams, whereby the speed adjustment for circular templates different Diameter achieved by a suitable choice of gear ratios becomes.
  • Similar rotary printing machines for large repeat patterns are in AT-311 289, DE-A-2 224 480 and DE-GM 73 32 801.
  • EP 0 396 924 B1 describes a rotary screen printing machine for printing large images using several synchronized in terms of their relative speed Circular templates, which can be selected according to a partial repeat can be lifted from their print position and onto the goods to be printed can be lowered and each with a single drive for template turning are provided. There is also a problem with this machine elaborate adjustment.
  • the invention is therefore based on the object of a rotary screen printing machine for printing large-format images, at a pattern change can be carried out comparatively very quickly and with which a very precise print quality can be achieved without that when upgrading or retrofitting the machine e.g. larger quantities of goods or loss of printing paste Need to become.
  • Each individual rotary drive and the acceleration are preferably Circular stencils at a speed that is synchronous with the printing blanket through a programmable control individually and incrementally relative adjustable to the other rotary single drives.
  • the individual drives are preferably - as known in principle from EP 0 396 924 B1 - by Stepper motors that can be operated continuously.
  • All drive and setting parameters can be controlled via the program control for a single circular template either from a central one Master computer unit or also via individually assigned parameterizable Specify and change control units.
  • Figure 1 shows a schematic functional representation, in the manner of representation corresponds to that of FIG. 1 in EP-0 396 924 B1, one for Printing of large-format images of a rotary screen printing machine, in the program-controllable individual drives for the individual printing stations with the simultaneous possibility is provided the round stencils / printing stencils of the printing stations individually and likewise programmable lifting and lowering.
  • a drive roller 14 and a tension roller 11 are provided for a rotating printing blanket 3 in the rotary screen printing machine. Furthermore, three printing units are shown as an example, which in a manner known per se only have printing stencils 4 indicated only schematically and each have a stencil drive pinion 12 mounted laterally and below the printing blanket 3 (the printing blanket).
  • the printing blanket 3 is driven via the drive roller 14 by means of a direct current motor 1, which is regulated by a converter 2, which is controlled analogously via a master computer 8.
  • a pulse generator 7, which is assigned to the tensioning roller 11 and which generates a digital signal f m corresponding to the speed of movement of the printing blanket 3, is provided as all the individual drives of the printing templates.
  • a frequency divider 9 connected downstream of the pulse generator 7 reduces the digital signal f m with a ratio that can be determined by the master computer 8 and feeds the corresponding digital signals to the master computer 8.
  • These digital signals are processed in the master computer 8 in a known manner to digital control signals which are supplied to a plurality of sub-computers (CPU) 6 corresponding to the number of printing templates 4 with a downstream power driver for a respective stepper motor 5.
  • the printing stencils 4 are driven with an angular position (phase position) that is exactly constant relative to one another.
  • Fig. 1 only three printing stencils 4 are shown with associated drive units; however, it is obvious that any number of stencils 4 can be driven in the same way.
  • each printing unit each printing template
  • the via a valve with pressure fluid that can be controlled digitally from the host computer 8 can be acted upon, the raised upper end position by a upper limit switch 13 and the lowered lower pressure position by a further limit switches 17 are determined.
  • the positioning of each Printing stencils are time-controlled, as explained in more detail below and depending on the setting of the limit switches 13, 17.
  • the position of the pressure unit raising / lowering can by potentiometer or electronic sensors e.g. inductive, capacitive, opto-electronic or done by ultrasonic sensors.
  • screw jacks 20 are provided can be driven via DC motors 21 or stepper motors.
  • a linear potentiometer 22 available, the readout value via a respective analog / digital converter 23 is given to the host computer 8 as a read-in value.
  • the linear potentiometer 22 could also be inductive proximity sensors be used.
  • All round templates 4 required for a pattern are upgraded and are at a standstill and raised.
  • the templates 4 become manual or with an automatic repeat determination positions that a non-engraved area is at the bottom, i.e. in Alignment with the printing blanket 3.
  • the templates 4 are then filled with printing paste in a known manner. Since on the Printing blanket 3 facing the bottom of the individual templates 4 each not engraved area, printing paste can not leak.
  • the printing methods possible with the invention are therefore also suitable for Printing pastes of different viscosities.
  • the pattern 32 shown in FIG. 4 should be, for example, a multi-colored one Print, as well as a cut line 30 or 31 in Direction of flow or print in front of and behind the pattern 32.
  • the pattern 32 have a maximum sample length of 500 mm, for example.
  • the repeat length the cutting lines 30, 31 can be variable.
  • the printing blanket 3 is set in motion.
  • To print the first cut line 30 to be printed becomes the assigned cut line template, So the first circular template 4 in area a - see time diagram 4 - depending on the pattern, but not depending on the position accelerated to synchronous speed with the printing blanket 3 and lowered at the same time.
  • At time b one under the Working magnet arranged (not shown) switched on, a roller or doctor blade inside the circular stencil 4 in a known manner Attracts way with predetermined magnetic force.
  • the cutting line 30 or 31 is printed.
  • the printing process is at the latest ended at time d, whereupon the printing template 4 in the Period e removed again and, if necessary, depending on the diameter and repeat length decelerated to a lower rotational speed or is stopped.
  • the template 4 assigned to the pattern 32 is lowered and at the same time at synchronous speed with the printing blanket 3 accelerates.
  • the working magnet assigned to this template becomes switched on.
  • the pattern becomes within the time slot g 32 printed, it should be emphasized that the pattern 32 also from the Print several stencils assembled, i.e. designed in multiple colors can be. If a multicolored print for the pattern 32 and / or the Cutting lines 30, 31 is desired, is a correspondingly higher To provide groups of printing stations.
  • the working magnet is switched off and the corresponding template is lifted off and again their diameter and the one to be printed Subreport accordingly in the period h to lower speed or delayed to a standstill.
  • the acceleration of the individual printing templates 4 and their lowering or lifting off controlled such that the individual template 4 at the first contact with the printing blanket 3, speed-synchronized with it and precisely positioned is in the repeat.
  • a repeat i.e. one large report each consists of a first cutting line 30 and the pattern 32.
  • the second Section line belongs to the second repeat below. Repeat length, Pattern length and template offset are variable. Of course you have to Repeat does not necessarily include a cutting line; he can also - how mostly - can be assembled from several equivalent templates.
  • the individual printing templates 4, such as the time diagram, are preferably 4 shows, already lowered in the non-engraved area, so that the magnetic force for lowering the roller or doctor blade can be switched on, and a color wedge forms in time, whereby stable conditions for good print quality are ensured, before the actual printing process begins.
  • the system arrangement according to the invention of a rotary screen printing machine can also be used for other coating and dosing systems, especially when using non-magnetic roller and doctor blade variants; i.e. the variant described here with magnetic roll or A doctor blade is not the only one to be adopted in connection with the invention Design variant.
  • a partial repeat is printed by a template 4, it is located the relative position of the template 4 to the printing blanket 3 again in one not engraved area, the working magnet is switched off again (see instants d, d ', d' '... in Fig. 4).
  • the template 4 in question is raised and delayed so that, for example, when the Standstill is again in the starting position.
  • the screw jack 20 via a lifting drive with stepper motor to operate instead of the DC motor mentioned.
  • the drive motor 5 with pinion 12 together with the template 4th is excavated so that a corresponding rappor wheel on the template and the pinion 12 are always in mutual engagement.
  • an eccentric or a Swashplate with stepper motor or with DC motor drive used become; in the latter case again equipped with a potentiometer and position sensors.
  • a rotary screen printing machine of the type according to the invention is closed to everyone suitable for printing or coating, but preferably for fabrics, woven goods, floor coverings, carpets and foils.
  • a rotary screen printing machine The type described here can also be used as a normal rotary screen printing machine (Endless repeat) and due to the possibility of image printing without mechanical changes also as a replacement for a planographic printing machine, is not only usable for large repeat pictures.
  • the setting and conversion of such a machine to different ones Pattern is through digitally keyed default values, correction and Change parameters very easy, so that no specially trained Specialist staff is required. Stencils that are not in the picture printing process can run normally during the image printing process Rotational printing (continuous repeat) are operated.
